Here's the first set of kanji! I hope this helps, and ik I said I would put romaji but tbh if you really want to learn, romaji won't help you, so set a goal to at least be able to read the hiragana. I know katakana can be a bit confusing when you start out, but keep practicing and you'll get there!
